| 摘 要： | 用单模压缩算子作用在单模奇偶相干态上即可得到单模压缩奇偶相干态.本文研究了这类量子态的四次方压缩特性,结果表明单模压缩奇偶相干态存在很强的四次方压缩特性,并且压缩程度随着压缩参量r的增大而增强.

| Abstract: | We can abtain the one-mode squeezed even and odd coherent states applying the one-mode squeezing operator on the one-mode even and odd coherent states.In this paper,the fourth-order squeezing effects of theses states are studied.These states possess strong fourth-order squeezing effects.And the bigger squeezing parameter r,the stronger fourth-order squeezing effects. |
